Filter by:Atherosclerosis and diabetes are related to coronary artery disease and peripheral artery disease. The mechanisms are related to increased reactive oxygen species (ROS) formation and inflammatory cytokine secretion. However, simply using antioxidant or anti-inflammatory therapies has no optimal outcomes. On the other hand, N-acetylcysteine (NAC) which has both antioxidant and anti-inflammatory effects could effectively attenuate ROS production and reduce vascular inflammation. Hence, we will investigate the effect of NAC treatment on the outcomes in patients with advanced atherosclerotic heart diseases and patients with diabetes combined with significant peripheral artery disease.
- General Objective To evaluate the effects of curcumin supplementation on cardiovascular risk markers, inflammation, oxidative stress and functional capacity in participants with coronary artery disease. Specific Objectives Assess, before and after supplementation with turmeric: - The nutritional status of the participants; - Blood pressure; - Atherogenic risk; - The expression of transcription factors (Nrf2 and NF-kB), antioxidant enzymes (NQO1, HO-1, sirtuin 1 (SIRT-1)), NLPR3 receptor, as well as the levels of inflammatory cytokines (IL-6, tumor necrosis factor-alpha (TNF-α), protein C reactive (PCR), IL-1, IL 18) and vascular cell adhesion protein 1 (VCAM-1) and E-selectin adhesion molecules; - Routine biochemical parameters; - Lipid peroxidation and oxidized LDL; - The 6-minute walk test, the recovery heart rate and the chair lift test; - Modifiable risk factors before and after supplementation; - The comparison of all parameters between groups.
The investigator hypothesizes that oxidative stress responses to West Nile virus infection in the central nervous system determine the severity of infection and the long-term neurological, neuropsychological and functional sequelae of West Nile Neuroinvasive Disease.
Skeletal muscle dysfunction is a frequent and clinically relevant systemic manifestation of Chronic Pulmonary Obstructive Disease (COPD), which is still poorly understood. Therefore, the focus of this study is on the role of a deficit in tetrahydrobiopterin and nitric oxide synthase uncoupling induced by chronic oxidative stress on metabolic and vascular abnormalities in skeletal muscle of patients suffering from COPD.
Investigators will test the hypothesis that chronic restoration of vagal nerve activity with a central acetylcholinesterase inhibitor improves insulin sensitivity and reduces adipose tissue oxidation in obese African American Women compared to white women.
The purpose of this study is investigate to the effect(s) of chronic occupational exposure to N20 and volatile anesthetics on the extent of oxidative stress (DNA damage and the generation of the biochemical markers) in operating room staff, with different levels of exposure to halogenated hydrocarbons, in comparison to unexposed controls (Intensive Care Staff), and to determine the relationship between the degree of oxidative stress and psychological stress, as assessed by validated psychometric measures.
